“…The lower Obtusum zone with Arnioceras semicostatum, as occurring in Europe, refers to a lack of MS, as in East-Central Mexico, maybe due to the same cause, which prevented the dispersion to Mexico. In South America, with regard to Pacific bivalve fauna, the communication and dispersion toward Europe since the Hettangian to the Pliensbachian was clear (Damborenea and Manceñido, 1979;Aberhan, 1994Aberhan, , 1998. With all this, it seems that at least this region of the Pacific had fewer disruptions of dispersion with Mexico, and also with Europe, which also shows the full range of the Sinemurian.…”

“…Particularly, Agerchlamys wunschae (Marwick) occurs in the Pliensbachian of New Zealand (Damborenea, 2002b). On the other hand, the genus Weyla is mainly a trans-temperate genus, commonly found along the margins of the Paleo-Pacific Ocean, both in low and medium paleolatitudes (Damborenea, 2002a Chile (Aberhan, 1992(Aberhan, , 1993 to the Neuquén Basin, reaching its southernmost occurrence at the Chubut Province (Damborenea and Manceñido, 1979;Feruglio, 1934;Wahnish, 1942). Representatives of Freguelliella and Pseudolimea show a cosmopolitan distribution (Damborenea, 2011).…”

“…A preliminary paleobiogeographical interpretation of the marine invertebrate fauna found at the Chubut Province may be suggestive of the existence of a shallow marine connection between the Western Tethys and the eastern Pacific as early as Hettangian times, related to the opening of a Mid-Atlantic seaway: The Hispanic Corridor (Damborenea and Manceñido, 1979;Damborenea et al, 2012;Ferrari, 2014a). Based on the genus Weyla, Damborenea and Manceñido (1979) proposed the hypothesis of the Hispanic Corridor as the main dispersion seaway for biotic exchange between these areas during the Early Jurassic.…”

“…Based on the genus Weyla, Damborenea and Manceñido (1979) proposed the hypothesis of the Hispanic Corridor as the main dispersion seaway for biotic exchange between these areas during the Early Jurassic. Vicente (2005) summarized the evolution of the Jurassic Andean retroarc basin at a global scale for the Central Andes, checking the time of the marine transgressions along the Andean region of South America and distinguishing two main gulfs through the arc from which waters f lowed simultaneously northwards and southwards in a narrow retroarc furrow; one of these gulfs was located at 35º S namely the Curepto Pacific Gulf (Fig.…”

ABSTRACT.A shallow marine invertebrate association is reported from a new Early Jurassic locality namely La Casilda, which is situated in the southwestern region of the Chubut Basin (Patagonia, Argentina). The marine deposits of La Casilda are located in the Río Genoa valley and bear a diverse invertebrate fauna including bivalves, gastropods, brachiopods, echinoderms and corals. A preliminary taxonomic analysis of the invertebrate fauna suggests that La Casilda deposits belong to the Mulanguiñeu Formation of late Pliensbachian-early Toarcian age, and may be coeval with those from the marine localities previously sampled in other regions of the Río Genoa valley. The preliminary results of a biodiversity analysis displayed that La Casilda is one of the most diverse localities at the Chubut Basin and could be assigned to the biofacies at the mixed siliciclastic-carbonate ramp proposed for the marine Early Jurassic at the Andean Basin of northern Chile. The evolution of the marine transgression during the early Pliensbachian-early Toarcian is also interpreted here in a time scale based on ammonite faunas, giving a preliminary temporal reconstruction of the entire Chubut Basin. Keywords: Invertebrates, La Casilda, Mulanguiñeu Formation, Chubut Basin, Argentina. RESUMEN. Una nueva localidad marina de edad jurásica temprana en la cuenca sudoccidental del Chubut, Argentina. Una asociación de invertebrados marinos de aguas someras se registró en una nueva localidad perteneciente al Jurásico temprano denominada La Casilda, la que se sitúa en la región suroeste de la cuenca del Chubut (Patagonia, Argentina). Los depósitos marinos correspondientes a La Casilda se encuentran en el valle del Río Genoa y comprenden una diversa fauna de invertebrados, incluyendo bivalvos, gastrópodos, braquiópodos, equinodermos y corales. Un análisis taxonómico preliminar de dicha fauna sugiere que los depósitos de La Casilda pertenecen a la Formación Mulanguiñeu, cuya edad es Pliensbachiano tardío-Toarciano temprano, y a su vez podrían ser coetáneos con los depósitos marinos de otras localidades muestreados previamente en el valle del Río Genoa. Resultados preliminares de un análisis de biodiversidad muestran que La Casilda es una de las localidades más diversas en la cuenca del Chubut y podría ajustarse a las biofacies correspondientes a la rampa mixta siliciclástica-carbonatada propuesta para la Cuenca Andina del Jurásico temprano marino del norte de Chile. La evolución de la transgresión marina que tuvo lugar durante el Pliensbachiano temprano-Toarciano temprano también se interpreta aquí en una escala de tiempo sobre la base de la fauna de ammonites, dando una reconstrucción temporal preliminar de toda la cuenca del Chubut.Palabras clave : Invertebrados, La Casilda, Formación Mulanguiñeu, Cuenca del Chubut, Argentina. 350 A new eArly JurAssic mArine locAlity from southwestern chubut bAsin, ArgentinA.

“…Although the genus is also present in the Tethys domain, it is recorded there only after the beginning of the Pliensbachian (Calzada, 1982;Liu, 1995;Fraser, Bottjer, & Fischer, 2004;Valls, Comas-Rengifo, & Goy, 2004). The genus originated in the Pacific margin and then extended to the western Tethys through the Hispanic Corridor or Proto-Atlantic (Damborenea & Manceñido, 1979Aberhan, 2001). See Damborenea and Manceñido (1979) for a complete distribution of the genus.…”
